Advanced Science, EarlyView.Selective CO formation in bicarbonate electrolysis is achieved by retaining reactive CO2 and tuning pH, while the competing hydrogen evolution reaction occurs at the interface. The rate‐determining step couples the chemical equilibrium of bicarbonate/CO2 with electrochemical charge transfer, offering insight into optimizing reaction conditions for ...

Operator Arithmetic-Harmonic Mean Inequality on Krein Spaces
Journal of Mathematical Extension, 2014 We prove an operator arithmetic-harmonic mean type inequality in Krein space setting, by using some block matrix techniques of indefinite type. We also give an example which shows that the operator arithmetic-geometric-harmonic mean inequality for two

Median as a weighted arithmetic mean of all sample observations [PDF]
This paper shows how median may be computed as a weighted arithmetic mean of all sample observations, unlike the conventional method that obtains median as the middle value (odd observations) or a simple mean of the two middlemost values (even ...

Advanced Science, EarlyView.We present a large‐area bidirectional human–machine interface integrating electrostatic multimodal tactile sensing with a dual‐resonant haptic actuator. The system enables linear pressure sensing that is decoupled from actuation and stable broadband vibrotactile feedback under dynamic contact conditions, supporting real‐time feedback modulation aligned

A Gauss type functional equation
International Journal of Mathematics and Mathematical Sciences, 2001 Gauss' functional equation (used in the study of the arithmetic-geometric mean) is generalized by replacing the arithmetic mean and the geometric mean by two arbitrary means.

Estimators for the Product of Arithmetic Means
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1962 SUMMARY Symmetric functions which provide unbiased estimators for the product of m population arithmetic means are considered for two sampling procedures: (a) m independently selected simple random samples, and (b) a simple random sample of multivariate observations.

Advanced Science, EarlyView.To overcome severe signal oscillation under extreme impact conditions, this work presents a Sensing‐in‐Energy microdevice which integrates a MEMS inertial structure directly within a supercapacitor electrolyte cavity. Utilizing shock‐driven transient contact and electrolyte damping for signal self‐filtering, it achieves weak‐oscillation, large ...

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections
Advanced Electronic Materials, EarlyView.The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...

A refinement of various mean inequalities
Journal of Inequalities and Applications, 1998 A new refinement of the classical arithmetic mean and geometric mean inequality is given. Moreover, a new interpretation of the classical mean is given and this refinement theorem is generalized.
